Hello,
I remember seeing something like this being asked before somewhere but I don't know what the answer was.
My question is, will it be too difficult to implement correspondence shogi (maybe as a separate server)? There are very few current options on the internet and they all feature westernized pieces which I find virtually unplayable. The site littlegolem.net has standard shogi pieces but only if you install a certain plug in. Also, the time for each move is too long (10 days initially, and if you almost spend it all, you only need play a couple of moves to recharge it to 10 days), so some games can last for months which is ridiculous.
The way correspondence is done on chess.com is very good in my opinion. You get to set the time for each move yourself when you make a challenge and also the rating range of your opponents, so you don't get to play against someone much better or much worse. You also have an analysis board where you can play and see the ideas you have in your mind (although this might not be good for improving calculation skills). It's also pretty easy to get engine analysis once the game is over.
I think correspondence is a pretty good way to get better. A lot of us are working from 9 to 5 and then go home to their families, and don't really have time to play long games which are necessary for improvement, so by playing correspondence we can devote a bit of time at work or at home every day to play a move or three. Of course, there's always an issue with cheating, but that issue exists with other time controls as well and is not something that can be avoided.

Thank you for your answer but I already know of that website, and as I said, it uses westernized pieces that I find completely unplayable, and can't stand. The website is also very outdated and unpleasant. I'm not interested in other websites. I'm interested in 81dojo having correspondence option, since it is by far the best shogi playing site out there, and as a programmer myself, I don't think it would require too much new code to implement.
